About Predictor.tips
Predictor.tips is an independent guide to prediction markets. We explain how Polymarket works, where it is legal, what it costs, and how it compares to alternatives like Kalshi, so you can decide for yourself.
What we do
We publish plain-English guides and live prediction-market odds. Every odds figure on this site is an implied probability pulled directly from the public Polymarket Gamma API, not a number we set. Our written guides are kept up to date as platforms, fees and regulations change.
How we research
Comparisons are based on each platform's published fees, funding methods and regulatory status, plus hands-on testing of the sign-up and trading flow. Where rules vary by location, we say so and point you to the in-app checks that give you a definitive answer for your own situation.
Independence & honesty
We are not owned by Polymarket, Kalshi or any other platform. We earn a commission if you sign up through some of our links (see our affiliate disclosure), but that never changes our verdicts. We tell you where a competitor is the better choice, including where Kalshi beats Polymarket.
Responsible trading
Prediction trading involves real financial risk and is for adults only (18+). Never trade money you cannot afford to lose. If gambling is affecting you or someone you know, support is available at BeGambleAware.org.
